How Often Should You Clean
Windows in Toronto?

The answer depends on where you live, what's around your home, and how much you care. Here's the honest breakdown.

The short answer: 2x/year is the minimum for most Toronto homes (spring + fall). But "most" doesn't mean you. Your specific neighbourhood, tree cover, traffic exposure, and home type all determine whether you need 1, 2, 3, or 4 cleanings per year.

1x/Year — Minimum

Quiet Interior Streets

Low traffic. Minimal trees. No construction. Interior lots away from major roads. Spring clean only — late April to mid-May after salt season.

2x/Year — Standard

Most Suburban Homes

Moderate traffic. Some mature trees. Standard exposure. Spring (April-May) + Fall (Sept-Oct). The "set it and forget it" schedule.

3x/Year — Recommended

Higher Exposure Homes

Near major roads. Mature canopy. Ravine-adjacent. Construction nearby. Spring + Mid-Summer (July) + Fall. Best for most GTA homes.

4x/Year — Quarterly

Premium / High-Exposure

DVP/highway adjacent. Active construction. Selling home. Allergy concerns. View-critical windows. Every 3 months — always clean.

Toronto's Seasonal Calendar

The annual plan that saves money: MANTLE offers recurring service plans — book 2, 3, or 4 cleanings upfront and save 10-15% per visit compared to one-off pricing. You pick the frequency, we schedule automatically. No forgetting, no last-minute scramble, and your windows stay clean year-round. See service plans →
When to add an emergency clean: Regardless of your schedule, add an unplanned cleaning when: (1) You're selling your home — clean windows add 2-5% to perceived value. (2) After renovation/construction — dust settles on glass and etches within weeks. (3) Before a major event (party, family gathering, listing photos). (4) After a severe storm — debris, mineral spots, and tree damage. A single emergency clean costs $150-$350 and takes 2-3 hours.
